Airtightness detection system of automobile pneumatic brake system and detection method thereof

Abstract

Provided is an airtightness detection system of an automobile pneumatic brake system. The system comprises a pneumatic brake system and an Internet of Vehicles system, the pneumatic brake system comprises an air pressure sensor used for acquiring air pressure data of a brake system front loop, a brake system back loop, and a brake system parking loop, the Internet of Vehicles system comprises a vehicle terminal and a networking platform, the vehicle terminal is electrically connected with the air pressure sensor, the vehicle terminal is connected with the networking platform in a signal manner, the vehicle terminal is used for receiving air pressure data transmitted by the air pressure sensor during vehicle shutdown and re-start and transmitting the air pressure data and moment data corresponding to the vehicle shutdown and re-start to the networking platform, and the networking platform is used for calculating a parking duration and an air pressure drop during a parking period, comparing the air pressure drop with a set threshold, and making an airtight determination. According to the design, the accuracy of airtightness detection of the pneumatic brake system is improved, and thereliability is high.

Description

technical field [0001] The invention relates to the field of automobile brakes, in particular to an airtightness detection system and a detection method of an automobile air brake system, which is mainly suitable for improving the accuracy of the airtightness detection of the air brake system. Background technique [0002] In the automotive industry, commercial vehicles that use compressed air as the energy source for the braking system use an air compressor to provide compressed air, use an energy storage device to store compressed air, use pipeline transmission, and use valves or components with various functions Compressed air produces the intended function. Since the energy storage devices, pipelines, valves and other components of the air brake system need to be connected through a large number of connection joints, there is a possibility of compressed air leakage. For serious leaks, the driver is easy to detect, and the sensors on the vehicle will alarm in time; but f...
